Hey there! So, "epicycle" is kind of a funky word, but I'll do my best to explain it in a way that makes sense to you. Okay, so imagine you have a bike wheel and it's spinning around. Now, picture a smaller wheel attached to that big wheel, also spinning. That smaller wheel is kind of like an "epicycle." It's a smaller circle that moves around inside a larger circle.

In the olden days, people thought that the planets moved in these little circles within their bigger orbits around the Earth. They called these smaller circles "epicycles." Later, scientists realized that the planets actually move in elliptical orbits around the sun, but the idea of an epicycle helped them understand how the planets moved for a while.

So, to sum it up, an epicycle is a smaller circle that moves around inside a bigger circle, and it's used to describe the way people used to think the planets moved in the sky. I hope that makes sense! If you have any questions, feel free to ask.
